The passage's entrance is hidden in a statue of Gunhilda of Gorsemoor. To gain entrance to the passage, one must give the password; Dissendium. Once the password is given, the hump on the witch's statue opens to reveal a short slide into a tunnel which leads under the school and takes about an hour on foot to get to Hogsmeade. Harry, Ron and Hermione ran past this statue in 1991 to avoid getting caught by Argus Filch.

Behind the scenes

In the handheld versions of LEGO Harry Potter: Years 1-4, this passage is much more elaborate than the simple straight passage of the books, being set up more like a maze and containing many fake walls leading to side areas.
